What’d I Miss?

OK, I’m posting The Commonly Confused Words Test because it played directly into my vanity calling me a genius and heaping praise upon praise onto me. But, I’m a little tweaked that it says I missed a few and then doesn’t tell me what it thinks I missed (or why it thinks I’m wrong). What the hell is that?! I would assume that the test is wrong if not for the fact that it’s so obviously correct about my greatness.
